Hi, My iPhone 6s not detecting any wifi signals, Is detecting and working for 1 minuets but after all the signals disappear I try everything reset networks, reset with DFU, change network settings but the same problem, Please what is the problem if it is a hardware problem what is the piece I have to change also there is no apple technical near me. Thanks Update (02/03/2021) Hi, I change it the wifi antenna but is the same problem

Take a look at the wifi antenna near the top of the logic board. Any issues with this antenna will greatly reduce iPhone’s ability to detect and connect to wifi networks. Hope this helps!
